ABSTRACT:
A photographic printer has a punch marking system for placing cut and end-of-order marks on the photographic paper. The punch marking mechanism is adjustable to accommodate different widths of print paper. The punch marking mechanism includes guide rods which are positioned transverse to the path of the print paper. First and second carriage assemblies are movable along the guide path defined by the guide rods on opposite sides of the center line of the paper path. A lead screw moves both the first and second carriage assemblies along the guide path in an essentially symmetrical manner about the center line of the paper path. Interchangeable inserts of different widths may be inserted between the carriages to define a spacing between the first and second carriages for a desired paper width. The punches or other marking devices are carried on the first and second carriage assemblies.
